Shipping personal things home
If you are considering shipping your purchase in GZ out to your e.g home country, here's what I know.
One of the option is to mail them out through their China Post, by Air or by Sea.
Not sure the Air freight rates but things involved in Sea Freight through China Post are:
1) You need to buy their specific boxes for the packing. Comes in small and large sizes. Large size is $11 RMB per box.
2) You must pack in front of the Post Office staff, under their camera. If you have packed nicely and sealed your box at home, they will have to open the box up to examine the contents.
3) A list of "not approved" items that you cannot post is being listed in the Post Office. Generally involves any fragile, breakable materials, chemicals etc. Of course, no pets! :D
4) Shipping cost charged by weight. Rates differs depending on which country you're shipping to.
5) There is a maximum number of boxes you can ship each day.
That's all I know. Hope it helps!
